I think it would be limited to Ukraine, until after the NATO counter-strike....if there is one.
That's the danger.
Once things go past Ukraine, all bets are off and the entire world risks hellfire.
Do NOT think Russia could not and would not incinerate 1000 cities.
In a short 3 hours span.
Its astounding how people are thinking its no big deal, for us to bomb Russians, on the very same battlefields of the eastern front. And their fantasy is that they’ll just back down and obey us. All these little brushfire wars have taught us the wrong lessons.
I don't see how the NATO air presence in the Baltic states and Romania aren't also attacked immediately, in part to preempt such a counterstrike.
That said, I doubt the homo-fascists in Brussels have the stones to take such an action in the first place.
